x80

x80 is a hexadecimal notation representing the decimal value 128. In computing, hexadecimal is a base-16 numbering system that uses sixteen distinct symbols, typically 0-9 and A-F. The 'x' prefix is a common convention to indicate that the following digits are in hexadecimal. Therefore, x80 signifies the hexadecimal number 80. This value has several interpretations depending on the context.

In the ASCII character set, x80 corresponds to a control character, specifically the Data Link Escape (DLE) character. This character is used in telecommunications and data transmission protocols for special control purposes. Beyond ASCII, x80 can represent a specific byte value. A byte is a unit of digital information that consists of eight bits. The value x80, when interpreted as an unsigned 8-bit integer, represents the decimal value 128. If interpreted as a signed 8-bit integer using two's complement representation, x80 represents the decimal value -128. The specific meaning of x80 is thus context-dependent, whether it refers to a character, a numerical value, or a specific bit pattern within a larger data structure.
